A To all 'whom 'it may concern.'

Be itknown that I, ANTON JOCH, a citi zen of the United States, residing at Cleveland, in the county vof Cuyahoga and State of Ohio,have invented a certain new and useful Improvement in Ventilators, of which the following is a full, clear. and exact description, reference being -had t the accompanying drawings.

This invention relates to ventilators and has for. its object the Vprovision of a device of this character adapted to-be located upon the roof of a building and which 'can be moved by the wind into the Iposition which is. most advantageous for its proper operation and at the same time be opened or closed from below,'the opening and closing means,

- being so disposed as not to interfere with its automatic orientation. Further objects and advanta es .ef this inventionwill appear .from the ollowing description and claims.

One embodiment ofthe invention is illus- -trated in the accompanying dra-wing` in 25 y which- Figure 1 is a vertical central section of the. device, the operating means being shown in elevation; Fig. 2 is a cross section taken on lthe line 2-2 of Fig- 1; Fig. 3f isa. cross sectional view `of theoperating means and the upper bearing; Figs. 4,/ 5 and 6` are crosssectionaly vi'ews of details, the same being taken upon the corresponding lines in Fig. 3.

Referring more particularly rto the drawing by reference characters, the "device consists of a stationary part A adapted to be attached to a roof or `pipe end," and a cowl B axially supported upon vthe vart A andadapted-to swivel thereupon. he part A is of cylindrical sha erand may beIlforrned of a sheet metal ban '1 having a base llaiigei 2 forattachment purposes. At a pointmidway of its length th1s part carries a spider .3 suitably attached thereto, as by rivets or bolts el passing through the sheet metal and through an exterior reinforcin band 5.

Rigidly attached at the centra point of this spider in any suitable manner, as Iby j clamp nuts 6 and-'7, is the upwardlyextending tubular support 8, preferably braced in .position by brackets 9'as.illust rated. The

cowl B-also comprises a sheet/metal casing v10 bent into substantially cylindrical form but having'one sidecut away and exk nde to form the laterally opening window' 1, the

sides of the window o ening meeting orti'on `are closed by plates) 13 fand- Specification 'of Letters Patent.' I i Patented May Application tiled September 10, 1910. Serial lio. 581,852.

volve. The lower portionv of the casing 10 is l made cylindrical, as at 19, and surrounds the upper end ofpart A with a slight clearance. rIfhe casing 1 is also provided with a secondv spider having legs 20 and 20* at a point between i'ts ends, .said spider being apertured.

at its center to surround the support 8 and prevent swaying. A collar 21 attached to the support v8 prevents removal'of the cas# ing. The u per end of the casing'isfclosed by means o a glass plate 22seated o'nj'an out-turned flange 23 and heldin place'by bending the edge of this flange up and over its edge, as at'24. I do not wishto confine myself .to the use of a glass plate but consider a vplate or cap of metal, whether of flat, rounded, or conical form as being'within my invention. The edges of the flange 23 may conveniently be serrated-to facilitate the attachment of the cover plate. The top plate 18 of the window portion carries a vertical vane 25 adapted to keep the cowl prop erly. directed with regard to'the wind in a lwell known manner, while a counter weight 43 attached to the opposite side of the casin balances the weight ofthe window, vane an louvers.

For the purpose of regulating the draft pivoted louvers 26 connected together by means of a-bar 27 so as to be moved simultaneously. The upper louver is provided on its outer face with a bracket 28to 'which is pivoted a. lever 29- which latter isprothrough the ventilator, I provide the win- #dow with a vertical series of horizontally opposite the 'lever 29 and to this bracket'l pivot the end ,of a bar 31, the othercnd of whiqh ,is pivotally connected to the lever 29. At itsl centraly part-this bar is split and spreadfso as tb surround the support 8, as shown in Figs. 2 and 6, lboth the branches ybeing-perforated at`kl32 to receive trunnions 33 carried by a sleeve 34 slidably and rotatably mounted uponl the support 8. This 'sleeve is provided at `itslowerend with a plurality ofdown--turned hooks 35V.whicli coperatein'supporting a cup-shaped ring 36 which surrounds a 'second sleeve 37 slidably mounted on the support 8. The upper end of this sleeve is langed outwardly as at 38, and between this flange and the ring 36 anti-friction balls 39 are placed. .yflhe support 8 has in its side a vertical `slot4() through which a bracket 4l projects,

'the outer end of this bracket being attached to the sleeve 37 and the inner end to a depending cord or chain 42.

In operation, if the cord 42 be pulled from-below, the sleeve 37 is drawn downwardly and carries with it the sleeve 34. This serves to depress the bar l31 and open the louvers 26. At the same time the free rotation of the cowl is not impeded since the cord 42 is axially arrangedand since the ball bearing minimizes the friction caused by thepull. Upon releasing the cord 42, the louvers close by their own weight.

Having thus described my invention, what I claim is:

1. A ventilator comprising in combina-y tion a rotatably mounted cowl, said cowl having a laterally opening window and a wind vane adapted to turn said window in the .direction to which the wind blows, louvers` in said window, a bar pivoted to the cowl at a point opposite said louvers and operatively connected to said louvers, and means connected to said-bar at the axis of the cowl, whereby the bar can be moved to operate said louvers.

2. A ventilator comprising inl ,combination a stationary part adapted to be attached to a roof, a tubular support extending vertically upward from the center 'of said stationary part, a cowl pivoted on said support, means carried by said cowl forregulating the draftv therethrough, a sleeve slidably mounted upon said support, aliexible member depending throughsaid support and attached to said sleeve, and connections between said sleeve and said regulating means, whereby va longitudinal movement of said sleeve upon said support shall operate said regulating means. -f
